Participants Instrument Data collection

6 II. Methodology

a. Participants

In the research site, there were eight teachers teaching science and mathematics. The subjects of mathematics, physics, chemistry and biology had two teachers each. Six teachers participated in the current study; two were mathematics teachers, two taught physics, one was a teacher of chemistry and one taught biology. Four of them are male and two are female. The range of their teaching experience was 1.5-16 years. The range of the participants’ English learning was 1.5-24 years, as some of them have already started to learn with English while they were in elementary schools. Only some of the participants had joined a TOEFL test and the score range was 493- 510.

b. Instrument

To gain the data needed for the study, a set of questionnaire was employed. The questionnaire consisted of five parts that were preceded by some questions to find out about the profile of the participants. The first part of the questionnaire part A was about the participants’ active use of English. Several questions in the questionnaire were taken from Estami and Fatahi’s research 2008. The second part part B was about the participants’ self-perception of their English language performance. The third part part C was about the participants’ attitude and motivation towards English. The fourth part part D was about the challenges that the participants faced when teaching sciencemathematics using EMI. The fifth part part E consisted of five open questions about the participants’ experience in EMI implementation.

c. Data collection

The data collection of this study began by sending a letter to the principal of the school asking for permission to conduct a study at the school. It was then followed by distributing questionnaires to the teachers of mathematics and science in CIP. There were nine questionnaire items given to the eight teachers of science and mathematics and to the program coordinator; however, there were only six questionnaire items returned on time and valid to be used as the source of data.
